Virtual numbers working principles

Scheme of virtual numbers forwarding process

A virtual phone number is a great example of modern communication technology. But what is it? and how does it work? The virtual number creates the illusion that a person’s location is in a particular country, but the owner can be situated far away: in another country, city, or even another continent. In addition, the user does not need to spend much money on phone conversations, as the rates are quite low. Heightened user convenience and greater connection quality are just some of the basic benefits of VoIP telephony, but there are many more.

How to set call forwarding to your virtual phone number:

  • SIP: Set your SIP login or just write "SIP" in the field for forwarding and we'll create an account for you. Call forwarding to SIP is free of charge for most countries.
  • Phone number: To set the call redirect feature to your number, you should input your number in an international format (without "+" or "00" at the beginning). Call forwarding to phone numbers is chargeable for all countries.

How to set forwarding for SMS messages using your virtual number:

  • Email: When setting this type of forwarding, you should input your email address. Forwarding to your email is free of charge.
  • Mobile number: To set up forwarding to your mobile number, you should input your number in an international format (without "+" or "00" at the beginning). SMS forwarding to telephone numbers is chargeable.
